technical field

Background technique

In modern decorative materials, with the improvement of people's living standards, ceramic tiles with three-dimensional concave-convex effect textures are becoming more and more popular in the market. Regularly distributed and irregularly shaped concave and convex adobes are then glazed and printed to achieve a concave-convex texture effect. With the development of 3D inkjet technology, most of the tiles with concave-convex texture effect produced at this stage are printed with ink with texture patterns on the body, and then glazed and sintered to form porcelain tiles with concave-convex texture.

In order to improve the gloss of the glazed surface of the existing ceramic tiles, it is necessary to adjust the formula of the glaze to make it have high light transmission, which also reduces the content of crystals in the glazed surface after firing and reduces the quality of porcelain. The wear resistance of bricks is low in Mohs hardness and easy to wear through.
